intermodulation

[‚in·tər‚mäj·ə′lā·shən]
(electronics)
Modulation of the components of a complex wave by each other, producing new waves whose frequencies are equal to the sums and differences of integral multiples of the component frequencies of the original complex wave.

Measuring harmonics and intermodulation is best done using a signal analyzer or spectrum analyzer so the level of the intermodulation signal in the presence of the transmitted signals can be seen.
A specific test configuration used to measure the third-order intermodulation product is shown in Figure 2.
The dynamic range of the spectrum analyzer must be at least 6 dB greater than the minimum allowed power level for the harmonic, the adjacent channel power level, or the intermodulation product.
In the past, this external amplifier had to have a 100-W or greater rating so it would not introduce intermodulation products into the test system.

Chapter 4 describes the system parameters for a typical receiver and transmitter, including noise, dynamic range, intermodulation products and adjacent channel power ratio.
This article derives a formula to mathematically predict the level of intermodulation products generated in a broadband, multi-carrier power amplifier.
